It's a nice and good smartphone, if it were not for the many bugs in the software. No additional settings, with WIFI, either always on or off. No precise battery indicator, schwanckt very, no percentage display, much of the battery time. Consumes an awful lot of Accu, even if it is in standby. For me, he has over 10 hours of standby 30% Accu consumed that goes not at all, for a smartphone in this price range. I appreciate that the new operation systems OS 10, is still in its infancy. The software is not yet mature, it looks in one year may be different from, because the idea is good, it just need to all the bugs are fixed. Especially at the Acculaufzeit they still need to work, especially in this price category. As I said, it's a nice smartphone, fast processor, good display, only the software could be better. I'll keep BlackBerry in mind when eventually the whole bugs are fixed, and they especially Acculaufzeit in Get grip, I will in my cell selection einbeziehen.Denn for a smartphone in this price Klaase the Z 10 is too weak again.
